MILFORD, MASSACHUSETTS, ASSIGNOR TO AMERICAN WRINGER COMPANY, OF VJ'OONSOCKET, RHODE ISLAND.

WRINGER.

To all whom it may concern Be it known that I, HENRY A. -JJnnsrnn, a citizen of the United States, residing at Milford, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in WVringers, of

I which the following is a specification.

This invention relates to certain new and useful improvements in wringers, and the primary object thereof is to provide improved means for locking and releasing the pressure bars, the latter carrying the two adjusting screws which function to tension the spring on the top roll, as usual.

The invention aims to provide looking or latching means which is tensioned so as to automatically lock or latch the bars when the latter are forced or moved into operative position.

A further object of the invention is to provide a latch which is of double character, i. e., is arranged to engage on each of the opposite sides of the bars and which in addition straddles the joint between and at the sides of the bars, to thus more effectively secure the bar against accidental movement or breaking of the joint thereof.

Still further, the invention aims to provide a latch which is of simple and economical construction and one which can be easily operated.

Other and further objects will be later set forth and manifested in the course of the following description.

In the drawings:

Fig. 1, is a front elevation;

Fig. 2, is a similar enlarged fragmentary view, showing the bar in inoperative position' Fig. 3, is an enlarged detail view of the latch, and

Fig. 4:, is a top plan view on a reduced scale of Fig. 3.

In proceeding in accordance with the; present invention, a vertically moving latch is employed which embodies a cross-bar l to which is connected a handle 2, the latter extending outwardly and upwardly and being curved as shown. The cross-bar carries a pair of side plates 3 which extend in the opposite direction from the handle and which are formed with hook-ends 4E shaped to engage a pair of pins or projections 5 which latter are mounted on the section A of the pressure bar, the latter including the sections A and B, connected by hinge H.

Specification of Letters Patent.

The side plates 3 are pivoted at 6 on opposite sides of the section B. As shown in Fig. 3 of the drawings the plates 3 extend across the joint between the sections A and B, and since a pair of pins 5 are employed and a pair of similar hooks 4, it will be apparent that a double latch is provided, i. e., the sections of the pressure bar are thus latched on each of their opposite sides. In order to hold the hooks of the latch in engagement with the pins 5, a spring 7 is employed which is secured on top of the section B and engages beneath the handle 2, so as to normally urge the hooks downwardly and into engagement with the pins 5. The free ends of the hooks 4 are formed to engage the pins 5 and then ride thereover during the movement of the sections of the bar from the position of Fig. 2 to that shown in Fig. 3, so that the latch is automatic in its action when the bar sections are moved to operative or extended position.

Preferably the spring 7 is located close to the pivots 6, so as to thus assure effective action of the latch structure in holding the pressure bar in its operative position. As shown in Fig. 3 of the drawing the plates 3 are formed with enlarged cheeks in order to provide for the reception of the pivot bolt 6 or the like. In order to release the latch, it will be seen that the handle 2 has such leverage as to enable same upon downward pressure being applied to easily force the hooks 4 out of engagement with the pins 5.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination with the hinged pressure bar of a wringer, and pins extending outwardly from one of the bar sections and on opposite sides thereof, a latch consisting of a cross-bar, side plates connected to the ends of the cross-bar and having cheeks at their inner ends and hooks at their outer ends the latter engageable with the pins, a handle extending outwardly from the inner ends and curved upwardly from the crossbar, means to pivot the cheeks to the other of the sections of the pressure bar and on opposite sides of the latter, and a spring interposed between the handle and the upperface of said other section of the pressure bar.

2. In combination with the hinged pressure bar of a wringer, and pins extending Patented Aug. 22, 15 22.

outwardly from one of the bar sections and on opposite sides thereof, a ]atch having it pair of hooks borne by the other section'of the pressure bar, and means to effect automesses rustic engagement of the hooks with the pins when the pressure bar is in extended position.

In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing Witnesses.
